Now I'm facing a big mystery.

That is...

Why does a man's nipple exist?

The trigger was biology class.

It was a class about the human body.

I suddenly started thinking about the functional reason for the nipple.

I couldn't stop.

Why didn't a man's nipple die during evolution?

Why?

Why?

Hey, Yagi.

It's good that you're studying hard, but the library is closed.

I'm sorry.

I'll be going.

Don't push yourself too hard.

Okay. I'm sorry for making you worry.

What's wrong?

I'm sorry. I'm fine.

What was he reading?

Yagi, you seem to be worried about something.

What's wrong?

It's not really a worry.

I'm just worried about something.

Something you're worried about?

Is it something you can't tell me?

I can't tell you...

What's wrong, Yagi?

Did I say something strange?

No, well...

What's wrong?

Is there something on my face?

Hey, Iyaki.

Iyaki.

Hey.

Hey.

Doctor.

Why do men have nipples?

What?

Nipples?

Because...

Nipples have a clear function of giving birth.

But men don't have that function.

Why didn't it evolve in the process of evolution of humans?

I don't know what to think.

Doctor, what do you think about men's nipples?

Men's nipples?

I'm not sure.

I don't know much about biology.

I don't want to hear about science.

Do you think men's nipples are necessary?

Well...

I don't want to say this.

Actually, I'm sensitive to nipples.

I don't want to lose my nipples.

You're sensitive to nipples.

In other words, you're a man who uses nipples sexually.

Well...

I don't know.

Doctor.

Can I touch your nipples?

For the sake of science.

No, you can't.

It's not good for teachers and students.

I can't move forward without answering this question.

Please.

No, you can't.

No, you can't.

Doctor, you're making a sound.

What?

How do you feel?

How do I feel?

I feel good.

I feel good.

I don't...

I want to know, I want to know, I can't stop

Want to know?

Oh, I see

How about this wrist?

That one?

That's right

Wow

How about that one?

Does it feel good?

Your wrist is a little stiff

Is it stiff?

Yes

That's right

Why?

Why?

That's right

When you feel good, it might get stiff

So there's a mechanism like that

That's right

Doctor

Can I touch you directly?

Directly?

Yes, yes, yes

Sensei, I haven't touched your nipples yet.

Oh, I see.

But I'm touching your ears now.

Sensei, it feels good.

Wow, it's around the nipples.

Yes, it is.

It might be so.

Sensei, can I touch you?

Yes, you can.

Nn...

Sensei, does it feel better than before?

F-F-Feels good...

Your voice is getting louder

F-F-Feels good...

I can't hold my voice...

And...

Your nipples are getting harder than before

Nn...

Your nipples are changing shape

Are they changing?

Nn...

Nn...

You're very strong.

Your nipples are very strong.

Mr. Rei, can I lick your nipples?

Oh, you can lick my nipples.

Oh, good.

Because you are a goat.

Your voice is louder than when you were touched by my fingers.

You look so comfortable.

I can lick you

and I feel good when you sit down

It's amazing

It feels good

Can I lick your lips?

Always.

When I saw the teacher's face...

I also...

I also felt a strange feeling.

Eh?

Sensei...

There's something hard on your elbow...

Doctor, what's wrong with this?

That's...

Doctor, my neck is weak.

If I touch my neck, it'll be like this.

I see.

The men's nipples and the men's genitals are connected.

I don't know.

If we touch it together, it'll feel really good, right?

Yes, it feels really good.

Can I touch it? For the sake of the surgery.

For the sake of the surgery?

Then I'll try it.

Doctor, how do you feel when you touch the genitals with your nipples?

I feel very excited and good.

I see.

Then...

What should I do?

Does it feel good?

It feels so good.

Your nipples are amazing.

Can I touch your nipples more?

Yes, you can.

Come here.

Ah, it's so hot.

Show me your happy face.

Do you feel good?

It's getting better.

When I touch your nipple, my body gets hot.

It's good.

・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・

Doctor, when I touch your nipples, I can see a lot of pus.

I...

I want to see your kind face

more closely.

Sensei's face...

Feels good.

Doctor, what's wrong?

I'm about to vomit.

Ouch!

Sensei, did you have a miscarriage?

Sensei, I want to know more about the male nipples.

Can I touch you more?

Sensei, I only shot you once, but your nipples are getting harder and harder.

Oh, I see.

If you lick my nipples, I'll get up right away.

It's harder than before.

I want to touch your neck more.

Yeah.

It's hot.

Do you feel good?

It's good.

It's good.

I'm sorry

I'm sorry

When I was in your arms

I felt my chest hurt

Your chest?

Sensei

Can you touch my chest?

No?

It's for the study

Ito?

I'm really nervous right now

Sensei, do you know my heart is beating?

Yes, I know. I can feel it.

I can't stop my heart from beating when I see your clothes.

Can you touch me directly?

Sure.

Please do it.

Sensei, my neck is getting stiff.

Doctor, how are you feeling?

Oh, I'm so tired.

Teacher...

Yes?

Please...

Let me live...

Yes...

Here...

I don't want to...

Ah, it feels good...

I'll keep looking...

Ah, amazing...

Yes...

I'll keep looking...

Yes...

Bye...

Yes...

I'm so happy.

I'm so happy.

I'm so happy.

I can't stop anymore.

If I touch your nipples and put them in the hot water,

it feels better, doesn't it?

That's...

It feels really good.

Is that okay?

Yes, it's okay.

It's not moving yet, but does it feel good?

It feels good.

What happens if I touch you while you are moving?

It's amazing. It feels good.

How do you feel?

Ah, it feels good.

It feels really good.

Don't look away.

Look at me.

If I touch you, you'll get stiff.

Ah, it feels so good.

It's okay to cry

My body...

It's so good.

It feels so good.

I'm watching you.

Where are you looking?

I'm looking at your face.

It feels so good.

It's hot.

I'm going to die.

It feels good, right?

It feels good.

It feels good.

My back hurts...

It feels so good.

It feels so good.

Doctor...

Can you do it from behind?

Yes.

I'm sorry...

Sensei...

I can't move...

Please...

Move...

A little bit...

I'm so nervous...

No...

More...

Move more...

Ah, amazing...

I want to see more of your face...

Doctor, are you going to have another surgery?

It's too painful.

I'm going to fall asleep again.

I hope you'll have another surgery.

I'm going to fall asleep again.

I want to have another surgery.

I'm going to fall asleep.

I can't. I'm going to fall asleep.

I want to know more about you.

I can't. I can't.

I can't.

I'm sorry.

I decided to touch various men's nipples to solve the mystery of men's nipples.

I'm always serious.

I'm sick of it.

I couldn't concentrate on my physical education class today.

What's wrong with you?

Actually, I have something to worry about.

It's good to concentrate on studying, but you have to do your best in the gym class.

I'm sorry.

I'm really sorry.

Hey, what are you laughing at?

Are you okay?

I'm fine.

Are you sick?

What are you doing?

Stop it!

Doctor.

What?

Even if you say I'm having a sexual harrassment,

I can't avoid it.

What are you talking about?

My nipples are...

Let go of my hand.

Stop it.

Let me touch your nipples.

What are you talking about?

Wait a minute.

It's so itchy.

I won't make you laugh.

What are you talking about?

Stop it.

I'm sorry.

I'm so worried about the power of men.

You can't do that.

Why?

You'll feel sick.

I'm fine.

No.

I promise to do my best in the gym.

I'll do my best.

Then, can I say that I was sexually harassed by the teacher?

I didn't know that.

It's good, isn't it?

Touching your nipples.

It feels good.

It feels good.

It's good.

If you feel it, it will be more pleasant.

What are you doing?

Stop it.

What are you doing?

It's not good.

Because I'm curious about the man's nipples.

I'm curious about it.

The teacher's nipples are very big.

Is it this big?

Did you forget me, teacher?

Did you forget me?

If I tickle you like this, will your nipples get bigger?

Yes, they will.

Then, can I make your nipples bigger?

No, you can't.

What?

Can I lick your big nipple?

If you lick it, it will be more pleasant.

Why?

Can't I?

Feels so good...

It's easy to lick your ears.

It's embarrassing.

No, you can't.

You like being petted, don't you?

Oh, no.

Can I touch your head more?

But...

Oh, no.

I feel sick.

Sensei...

You're hitting something on your elbow.

This is...

I want to see your nipples.

What are you talking about?

No.

Is it okay?

Even if you say I'm sexy?

That's...

No.

Take it off.

I know.

It's good to be together.

Why do you know?

Tsukubi-chan, you have a cute face.

Can I lick your cheek?

Yes, you can.

Wow...

I put a lot of it in.

You're big.

No, I can't.

You can still go.

No, I can't.

I can't go any further.

I want to see you feel better.

No, I can't.

I like this one

I like it too

You did it.

No.

You're not going to go out?

I'm not going out.

I'll do my best for the next physical education class

So can I touch your nipples again?

O-okay

Doctor, do you want me to touch your neck?

Please, please, please touch me.

Well, then, will you consider my grades in the club?

Of course, I'm a regular member of the club, and I'm going to play a big role in the tournament.

Please, please, please.

Doctor...

Doctor...

This is what I wanted you to do.

You can leave the rest to me.

Please.

So, leave it to me.

Yes.

I'll make your neck feel better.

Please.

You're so nice.

That's me.

It feels good.

You really like your nipples, don't you?

Yes, I love it when you touch me here.

How?

You're so kind and hug me.

You love me so much.

If you do this, I'll get a cold.

Yeah, yeah, yeah.

Yeah, yeah, yeah.

Yeah, yeah.

Yeah, yeah, yeah.

Yeah, yeah, yeah.

You too.

I'm sorry.

You're so stiff.

Yeah.

Yeah.

Doctor.

You look like you're in pain.

Yeah.

I'm all swollen up.

Do you want me to take this off?

Is it okay?

Yes.

I'm sorry for being a pathetic teacher.

But I can't help it.

It feels good.

It's okay, teacher.

I've been able to understand the man's need.

Oh, really?

I'm glad.

Oh, that's great.

Oh, it's hard.

Oh, that's great.

Oh, that's great.

The teacher is moving a lot.

I'm reacting to the sound of the Piku-Piku.

It feels good.

Oh, it feels good.

Oh, I'm so scared.

I'm so scared.

I'm so scared.

I'm not strong enough.

I can't do it.

Not yet.

Really?

Let's do something more pleasant.

Okay.

Sensei, do you want to be a horse?

Yeah, yeah.

More?

You want me to be more?

I want to be a horse.

Then,

become a horse here.

I can't do it.

I can't see, so I'm nervous.

Oh, my back is warm.

Is it warm?

Yes.

Is it warm?

Yes.

It's soft.

Oh, my back is warm.

Yes.

Oh, my back is warm.

Yes.

It's good.

It's good.

It's good.

Yes.

I'm sorry.

I'm sorry.

I'm sorry.

I'm sorry.

It feels good to be strong and weak.

It feels good to be strong.

I'm sorry.

I'm sorry.

I'm sorry.

I can't do this anymore.

I'm going to collapse.

I can't do this anymore.

Do you want to be a comfortable person?

You want me to be comfortable?

Yes.

I'll be patient.

You look comfortable.

Thank you.

I want to say something to you.

Don't say it yet.

Uuuu!

Sensei, if you make that noise, someone will come.

I'll go out.

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Uuuu!

Sensei, if you make that noise, someone will come.

I can't stand it.

Uuuu!

I see.

Uuuu!

Uuuu!

It's so good.

Is it good?

It's so good.

Your neck is really sensitive.

It's amazing.

It's totally different from my fingers.

Does it feel good?

Yes, it does.

I'll do anything for you.

I'll do anything for you.

Doctor, you have a lot of juice.

I'm holding it in.

It'll come out.

I'll lick it.

Licking? I'm embarrassed.

You don't like it?

No, I don't.

Is it okay?

I love you.

I'm so happy.

I'm so happy.

I'm so happy.

I'm so happy.

No, you can't let it out yet.

Teacher, don't you want to do something more pleasant?

No, I want to do it, but...

Don't you want to put your hand in here?

No, of course not.

While I'm here,

I want you to touch my delicate nipples.

I'm sure you want me to.

I'm going to sleep.

Really?

I can't stand it.

I can't stand it.

I can't stand it.

You fell asleep.

Doctor, I think you'll be able to get it out soon, so I won't move yet.

I know, but I can't touch your neck so much.

I can't.

I can't.

You don't want to?

I might be able to get it out with just this.

You don't want to?

No.

Do you want me to do it?

I'll be patient, so I want you to do it.

It's so hard.

It's so hard.

I'm sorry. I'm not good at this.

You're not bad at all.

Please teach me more.

It's so hard.

When I touch your neck, it gets harder.

I can't move at all

I'm so sorry.

I'm so sorry.

I'm so sorry.

I'm so sorry.

Really?

Yes.

Sensei, more...

More?

More...

I'm sorry, I'm not drunk.

I'm so happy.

I'm so happy.

No, I want to do it again.

I got it.

I'm hungry.

Look at me.

I'm looking at you from the back.

I'm looking at you all the time.

I've been holding it in for a long time.

Can I do it just once?

I don't know if I said that.

I'll make you feel better.

It feels so good.

I feel so much better.

Happy birthday!

Yeah

Oh, that's dangerous

I'm going to fall asleep

I fell asleep

I can't stand it if you do this.

When the video is over, I'll kiss you.

Yagi, I'm sorry to bother you while you're studying, but it's time to close the library.

What? Isn't it a little more?

It's a very interesting place now.

But I have to look around the teacher.

Sensei?

Hm? What?

If you say so, I won't touch your nipples anymore.

What? No, Yagi.

If you don't touch my nipples, I'll die.

Then...

So...

Can I stay in the library a little longer?

Can I?

Yes, of course.

Wow.

Wow.

I want to stay here longer.

Can I touch you directly?

No, I want you to touch me directly.

Then I have to take off my clothes.

Yes, take off your clothes.

Does it feel good?

Yes, it feels good.

Yes.

It feels good.

I'm glad I was able to put a lot of books in the library thanks to you.

Ah, that's good.

Then, touch me more.

Yes.

I'll touch you a lot for that.

Yes, please.

Yeah.

Do you want me to touch your tongue?

Yeah, I want you to.

I have to take off my clothes.

I'll do it right away.

I'm sorry.

Yeah.

Do you want me to touch you?

I want you to touch me.

You feel good when I tickle you like this, right?

Yes, I feel very good.

Is it the same as the tickling of the nipples?

Yes, I feel good.

Sensei, your mouth is full of my juice.

Hey, can you bear it?

No, I can't.

Do you want to let it out?

Yes, I do.

Then, I'll do it like always.

Do it, do it.

Sensei, you love me, don't you?

I'll look at your nose when you breathe out.

Okay.

Wow, that's amazing.

I'll make it clean.

Mr. Kuroda, you're still big.

My eyebrows...

I can't do it anymore.

I can't move my eyebrows.

Mr. Kuroda, you can't do it.

I can't do it.

I can't do it.

I can't do it.

I'll make you feel better.

Yes.

Hee hee.

Hey, doctor.

How about this?

Eh?

Ah, yes.

Can you see the sun?

Don't you feel hot?

Oh, it's so hot.

It's okay. I'll do it again.

Great.

Like this?

Harder?

Yes, like that.

It's so hot...

I'm gonna fall asleep...

It's okay, I'll take off my clothes.

It's so hot...

Doctor, you put a lot of it again.

Yes.

Then, I'll clean it again.

Then,

after this,

you can use the library, right?

I will tell you my opinion on the man's nipples.

It is...

Men's nipples are...

a tool for women to control men.

Whether my opinion is correct or not...

will be the answer to the comfort of future school life.

I can't help but look forward to it now.

Yagi...

Today...

I have something to tell you.

What is it?

Well...

I saw it.

In other words...

When I was leaving the infirmary...

You were...

with another teacher...

You were...

with another teacher.

Did you see it?

So...

What did you talk about?

You...

You shouldn't have...

You shouldn't have done that.

There is a difference in age between students and teachers.

This is a study room.

Teacher...

Don't be so impolite.

You...

want me to touch your nipples, right?

What?

What?

I can understand...

a man with a weak nipple.

No...

I...

I don't...

I don't have that kind of feeling.

Yagi...

Yagi...

Hey...

Hey...

Why?

Is it easy to understand if it's a woman's intuition?

No...

It's not a theory, I understand it.

No...

Show me more of your strange appearance.

You can show me everything in front of me.

I feel sick.

Doctor, should I take off my shirt?

Maybe.

I'll take it off.

What about the shirt?

I'll take it off.

I want you to touch my neck.

I want you to touch it.

You had such a big nipple, right?

Cute nipple...

It's already hard.

I...

Hey, do you want me to touch you more?

I want you to touch me.

I want you to touch me.

Then, doctor, lie down on the bed.

Yes.

Yes.

Do you feel your neck is getting bigger?

Yes.

I want you to do more.

Yes.

Yes.

Show me your embarrassing face.

Yes.

Yes.

Yeah

Yeah

Yeah

Yeah

Yeah

Yeah

Yeah

Yeah

Yeah

Yeah

Yeah

Yeah

What?

Do you want me to lick you?

I want you to kill me

You've become honest, Sensei.

How cute!

Does it feel good?

It feels good.

Please lick me a lot.

Yeah.

I love you.

Yeah.

Yeah.

You look like you're in pain.

I'm in pain.

It's painful, but...

Can I keep it open?

No, you can't.

You can take it off.

You like being with me, don't you?

I love you, Hana.

Yeah.

Yeah.

Yeah.

Doctor?

Yes?

Can I touch your nipples in a more difficult way?

Sure!

Please be a horse

Horse?

I'm a horse

Doctor, you're in a very embarrassing situation.

But I'm happy.

I'm so happy.

It's strange that you're doing this to me.

Doctor, what should I do?

I might be able to take your nails off.

You don't have to.

Oh, I'm so tired.

Doctor, I...

I want to touch your face while looking at it.

Show me your face.

Can I lick your nipple?

Please lick it.

Ah... What is this? I can't stop it.

Phew...

I'm not in pain at all.

I'm not in pain at all.

Do you want me to rub your back?

Yes, please.

Pfft...

There's a lot of blood coming out of your nose.

What's wrong?

What's wrong?

What's wrong?

Please give me a kiss.

Doctor, it's getting very hot.

Here we go.

But...

I want to touch your nipples more

Is that okay?

Doctor, is it okay to end this?

I want to continue.

I know.

Because you're getting bigger.

Let's touch each other.

Do you feel your neck is getting harder?

Yes, it's hard.

Yes, just like you.

Yes.

Doctor,

will you do my hair too?

You want to do it?

Yes.

Delicious!

Munch!

Munch!

Munch!

Munch!

Munch!

Munch!

Munch!

Munch!

Munch!

Munch!

Yeah

Yeah

Yeah

Sensei licked my boobs

and I got wet

Sensei

Ah, it's warm.

I can't stop.

I love you.

I love you too.

Doctor, don't you want to put it here?

I want to put it here.

I want to put it here.

I'm going to touch you a lot.

I'm going to touch you a lot.

I'm going to touch you a lot.

I can't breathe...

Come here, come here, come here...

I'm sleepy...

But, doctor, it's still too high.

I'm already...

You'll get out, won't you?

I can't do it anymore.

I had an unbearable experience.

Thank you, but I can't get out.

I'm sleepy...

Ah, Sensei...

I'm still going to sleep...

I'm going to put a lot on your face.

Let's go!

Let's go!

Doctor, can I come to your office again to touch your nipples?

Of course.
